Pembrokeshire council said home owners and businesses in Haverfordwest town centre should prepare for possible flooding on Friday night, while Carmarthenshire council warned those in the St Clears area to be “particularly prepared”.

A number of roads were flooded including parts of the A40, which runs through both counties. It has flooded between Fishguard and Scleddau, and Llanddewi Velfrey and Penblewin.

Taxis replaced trains between Haverfordwest and Milford Haven, while Traffic Wales reported people were evacuated from Lower Priory due to most roads being flooded.
